* Skyped Andy vs Fabiana - trying to get an idea of the structure of the raw data files and make sure that the extracted text files are ok. Seems everything is ok, header log file contains all header info (albeit in a strange format). Different version files have different info, eg, some versions have the SD of the data others don't. Need to consider when extracting/analysing that the number of columns etc are going to vary from file to file.

According to andy need to
